Managing wireless transmission capacity

The present invention generally relates to broadcasting content using wireless transmission capacity.

Figure 1 shows the traditional architecture of broadcasting events in real time or near real time (live) on a television or rich media device. This architecture provides some fundamental inconvenience for TV producers, mobile TVs, IPTVs (Internet Protocol TVs) and Internet TV providers, such as huge logistic costs and low flexibility.

In the architecture shown in Figure 1, broadcasts of event 100 (eg, TV broadcasts) that are local or regional (eg, national) important have the location of the event the mobile control unit 103, commonly known as a satellite track. Need to be deployed. The mobile control unit 103 processes the image taken by the camera 102 (and transmitted to the mobile control unit 103 via the cable connection 104) to the TV station hosting the master control room (MCR) 107a, 107b. Send.

Small to medium-sized media production companies, IPTV, Internet TV and mobile TV providers, who usually do not have the financial resources to invest in their own broadcast equipment, have the resources they need from the large TV broadcasters founded. Must be borrowed. The costs associated with renting, deploying and maintaining such equipment are profit-oriented and difficult for a category of media production company to enter or establish in the live event broadcast market.

One of the biggest cost factors comes from the transmission of video signals, in addition to the equipment needed to broadcast the event in real time. That is, . Microwave (digital / analog terrestrial) is used between the mobile control unit 103 and the local / regional TV station MCR107b that sends the encoded TV / video signal to each destination network 109b via the TV broadcasting tower 108b. What to do (indicated by arrow 105b); and / or A communications satellite between the mobile control unit 103 and the remote TV station MCR107a, which sends encoded TV / video signals to each destination network 109a via the TV broadcast tower 108a. Use 101 (indicated by arrows 105a and 106).

<p> One potential condition in which lack of flexibility has a negative effect is in addition to the main event, a number of secondary events, namely interviews in the locker room before and after the game or around the location of the main event. Live reports are usually done. These secondary events are of almost the same importance to the end consumer as the main event. Due to the size of the device and the required accessibility between the camera and the movement control unit (for retransmission), it is not always possible to provide this information to the end consumer in real time.</p>

<p> With respect to this application, the term event should be broadly interpreted. The term event is not limited to covering only short, one-off type events such as football games, but is understood to be anything that can be covered by a contract that defines the geographical scope and duration. Must be done.</p><p> In the architecture shown in FIG. 2, a real-time broadcast of event 100 is configured such that a wirelessly enabled TV camera 202 sends a wireless signal 203, for example, to base station 201 of a wireless network, which is a cellular network. .. The base station 201 uses a known method to transmit data via the communication network 210 (204) and to the TV stations 107a and 107b via the connections 205a and 205b. The TV stations 107a and 107b perform a process of sending the encoded TV / video signal to the destination networks 109a and 109b via the TV broadcasting towers 108a and 108b.</p><p> This architecture is facilitated by the following technical factors: Deploy LTE-like wireless networks across the globe to provide the quality of service required when transmitting live TV streams over the air. -A new TV camera that combines wireless features such as the cellular model is available. These cameras can send captured images directly to a destination platform over a wireless network.</p><p> The use of conventional satellite or microwave electronic news collection trucks (reference number 103 in Figure 1) is not required. The associated costs and efforts can be reduced, the investment cost is low due to the inexpensive equipment, and the operating cost is low due to the simplicity of the new mobile camera set.</p><p> The combination of these two factors provides a wide range of benefits, including reduced logistical efforts and reduced transmission costs. The cost of transmitting content over satellite is very high compared to the price of a similar bandwidth handle LTE uplink connection that uses a large number of SIM cards for the camera-embedded modem.</p><p> According to a first normative aspect of the invention, in a method for managing wireless transmit capacity, the available wireless transmit capacity obtained from the wireless transmit capacity provider is stored in the server; to a first user.

A method for managing wireless transmit capacity according to normative embodiments will be described with reference to FIG. The capacity can be used to provide media coverage for the event via streaming or other broadcast methods.

In step 301, the mobile network operator, or someone authorized to allocate wireless transmit resources (eg, mobile virtual network operator, MVNO), is with the broker service provider represented by the server (detailed with reference to FIG. 4). , Agree on available wireless transmission capacity for its broker service provider. As an example, the operator provides the broker service provider with information about bandwidth, time and place, that is, where, when and how much bandwidth the broker service provider has in its disposer. In the simplest form, the operator agrees to give some bandwidth to the entire area of its network 24/7. Alternatively, the operator gives the broker service provider only the capacity that it is unlikely to sell on its own. For example, the operator holds the total capacity or a portion thereof during peak hours and gives the broker service provider only the remaining capacity, and / or the operator gives the broker service provider at least a portion of the capacity at the specified location. You may refrain from giving.

In steps 302a and 302b, the broker service provider is informed about the time and location of the event requiring wireless transmit capacity, as well as the required bandwidth. The event organizer informs the broker service provider about the time and place, for example, that a football game will be played at a stadium at a certain date and time (302a). If the event organizer is also responsible for live broadcasting of the event or knows the bandwidth requirements, it also identifies the required bandwidth requirements (302b). However, bandwidth requirements may be communicated by the media company (or provider) responsible for covering the event. The media company finds the need to cover such events from said broker service provider and offers those services to the event organizer, or the broker service provider suggests bandwidth and the event organizer or media company is the customer's It is also possible to respond with bandwidth requirements as a role.

In a normative embodiment, the information given in steps 302a and 302b includes, for example, the following information: -Name of the event to be hosted (eg London Olympic games, soccer) -Event description (more information) -Category (category to which the event belongs: sports, music, politics, etc.)-Start: Event start date and time-End: Event end date and time-Address: Main address where the event takes place-Coordinates: GPS coordinates that identify the geographical location where the event takes place-Radiation: Radial that exits the main address and defines the geographical area covered by the event Bandwidth: Bandwidth requirements

Based on the information received in step 301, the broker service provider knows the available wireless transmit capacity. Broker service providers use, for example, the capacity area grid described below. In step 303, the broker service provider determines if there is capacity to meet the bandwidth requirements of the event at the indicated location and time.

If the available wireless capacity is found, the broker service provider makes an offer to the event organizer or media company in step 304. Offers take different forms, based on how the broker service provided by the broker service provider was established. If the broker service has a web-based interface for the customer to enter their needs, the offer is simply a new pop-up window asking the customer whether to handle the offer and accept or reject the offer. .. The broker service, on the other hand, may be fully automated, in which the offer is made between two pieces of software, one running on the broker server and the other running on the customer equipment (this practice). In form, customer means event organizer and / or media company). Communication between the operator and the broker service provider can be performed as well.

In step 305, the customer accepts the offer (or part thereof). If the broker service provider suggests bandwidth in the offer, the customer accepts, for example, all or part of the offered bandwidth (if this already meets the customer's bandwidth requirements).

In step 306, the broker service provider reserves the capacity accepted in step 305. This is done, for example, by updating the capacity area grid, as described below.

The time between capacity reservations, actual events and capacity allocations varies significantly. Based on the practice, the allocation will be made immediately after the reservation or a few months after the reservation. For this reason, the broker service provider can make a final check on the available resources shortly before capacity is allocated, simply to ensure that the resources are actually available (step 307). This check is performed by utilizing the capacitive area grid described above and below.

In step 308, the broker service provider sends a request to the operator to allocate the reserved capacity. The reserved capacity is allocated to be used to cover the reservation. Assignments are performed in certain normative embodiments by modifying the priority of at least one user identity in the database. The database is a subscriber policy database or other network element that can store subscriber priority related information. In the case of LTE networks, the function that maintains the database is, for example, a policy and billing rule function (PCRF), a home subscriber server (HSS) or a packet data network gateway (PGW). In one normative embodiment, the policy applies the service format attached to at least one user identity to the policy and billing rule function during the booking period (so that the priority associated with that service format is also selected). It is corrected by setting it in "Conversation video". A guaranteed bit rate radio resource format can be used. The at least one user identity here refers to the user identity in the user identification module of the cellular model camera used to capture the event.

FIG. 4 shows a device for managing wireless transmission capacity according to a normative embodiment. This device includes a broker server 401. This broker server 401 includes a processor (CPU or similar) 403. The broker server 401 also includes a memory 404 connected to the processor 403. Processor 403 is configured to run broker server software stored in memory 404 to control the operation of broker server 401.

The broker server 401 further communicates with the network of the event organizer or the media company 420 via the connection 407, and also communicates with the network (operator network) 410 that provides wireless transmission capacity, such as the LTE network, via the connection 408. It also has an input / output system 402 (or communication module).

The broker server 401 also comprises a database 405 that stores a capacity area grid or the like, with the help of which the broker server 401 maintains available wireless transmit capacity and its reservations.

The operator network (cellular network) 410 includes a database 411, such as a PCRF database for LTE networks. As mentioned above, the database is a subscriber policy database or other network element (such as HSS or PGW) that can store subscriber priority related information. When the broker server 401, which is a server outside the operator network 410, requires the operator network to allocate wireless transmit capacity in certain normative embodiments, the PCRF database, HSS or PGW, depending on the implementation, is used as described above. Will be done.

FIG. 4 further shows two wireless cable cameras, namely cellular modem cameras 102a, 102b, in which user identities are provided on user identification modules 402a, 402b, such as SIM cards. A user identity in a user identification module represents a user of a wireless transmission system, i.e., a user who requires wireless transmission capacity (or wireless resources) to communicate data such as video / TV signals. Authority 430, shown in the fire engine in Figure 4, also has wireless transmission features, such as a cellular modem with user identity 432. Authority 430 is a high priority customer (or user). Therefore, if authorities require wireless transmit capacity, this need negates the wireless transmit capacity needs of other users. Instead or in addition, there are other high-priority customers. If, in one normative embodiment, a high-priority customer requires wireless transmission capacity, then the high-priority customer will have the required capacity, as detailed below.

FIG. 4 also shows a second operator network 440, such as another cellular network. This second operator network is operated by an operator operating the network 410 or by a different operator. It is an LTE network. In one normative embodiment, the second operator network 440 is used to provide additional wireless transmit capacity for the user if the wireless transmit capacity provided by the (first) network 410 is exhausted. To. The second operator network 440 comprises a database 441 such as PCRF, HSS or PGW for LTE networks. This database is a subscriber priority database or other network element that can store subscriber priority related information. The broker server 401 communicates with the second operator network via connection 406.

FIG. 5 shows the form of the capacity area grid according to the normative embodiment. The cells of this capacity area grid are basically the cells of the map grid that identify the geographical location, here the location or cells A1-C6. In each grid cell, the broker service provider maintains as a function of time information about how much capacity is available for sale and how much is already reserved. This is further illustrated in the capacity area grid usage scenario in Figure 6A-6D.

FIG. 6A shows an empty grid before the available wireless transmit capacity is received from the operator, all cells are always available = N / A and reserved = N / A.

Figure 6B shows that the broker service provider has received the available wireless transmit capacity from the operator, but has not yet made a reservation, and all cells are always available = 10MB and reservation = N / A. Shows the capacity area grid of the state. Figure 6B assumes the simplest case where an operator (always) gives the same resources to all networks 24/7. In fact, it should be noted that operators want to change the capacity given to broker service providers based on location and / or time. This is fully supported by the grid, but is omitted here for the sake of clarity of the examples.

Figure 6C shows a capacity area grid where the broker service provider receives the available wireless transmit capacity from the operator and also reserves for the user. The broker reserves 5MB capacity for user A at time 07: 00-09: 00 at location A3, and reserves 2MB capacity for user B for the entire network after time 08:00. The capacity area grid shows how much capacity is still left in each cell.

One normative embodiment provides a broker service provider with a way to handle the exhaustion of available wireless transmit capacity. The determination and handling of such conditions is described below with reference to FIGS. 6D, 7 and 8.

Figure 6D shows a situation in which a high priority user or application, such as Authority 430 (Figure 4), notifies that it needs some wireless transmit capacity. For example, as shown in Figure 6D, the broker service provider receives an instruction from a high priority user (User C) that 5MB of bandwidth is required after 08:00 in cells A2 and A3.

Using a capacity area grid, broker service providers typically go through an automated process and, even if capacity is available in location A3 from 08:00 to 09:00, in most locations the available capacity is Detects inadequate (601).

A method for managing a state in which a high-priority user finds that he / she does not have sufficient resources will be described in detail below with reference to the flowcharts of FIGS. 7 and 8.

The broker service provider receives, for example, the available wireless transmit capacity through the procedure described with reference to FIG. 3 (step 301) and stores it in the capacity area grid or the like in step 701. The broker service provider reserves capacity for users A and B in step 702, for example, by using the procedure described with reference to FIG. 3 (steps 303-306). In addition, the broker service provider updates the capacity area grid in step 703, for example, using booking step 306 described with reference to FIG. 3 to reflect how much capacity is still available.

Then comes the additional demand for wireless transmit capacity (step 704). The broker service provider receives this request from a higher priority user (or a user with a higher priority than the current user). For example, a broker service provider agrees with government officials / authorities that public safety officials such as police and fire departments must have immediate access to the required wireless transmission capacity. In an imaginary state, for example, at 08:00, a major accident occurred at the event described here, and a public safety official (User C shown in Figure 6D) went to 5MB capacity in cells A2 and A3 until further notification. Request access to. This is, for example, to ensure uninterrupted public security communications.

In step 705, the broker service provider detects that there are not enough resources (wireless transmit capacity) to satisfy User C's request, for example by using the capacity area grid described above with reference to FIG. 6D. .. In step 706, the broker service provider takes action to increase the resources available to user C.

In one normative embodiment, the broker service provider uses a more sophisticated algorithm to determine which user to prioritize. These algorithms include parameters such as how much bandwidth each user uses and / or what priority level they assign to the applications they run. For example, an application labeled "Safety Civil Servant" is assigned a high priority, and an application labeled "Media Coverage" is assigned a low priority.

Several embodiments that increase the wireless transmit capacity for User C will be described with reference to FIG.

In step 801, the broker service provider notifies user A and / or B of the lack of available transmit capacity. Also, in certain normative embodiments, User C is also notified of the lack of resources. This is because even if actions are taken to increase the capacity available to User C, they will, for example, make the connection time slightly longer than if the capacity were immediately available. In response to this message, in one normative embodiment, the notified user initiates to reduce bandwidth usage or locally store data to be transmitted until sufficient capacity is available again. .. If the message is only sent to user A, it is all about getting more resources for user C. In such cases, the broker service provider immediately jumps to step 804 to update the capacity area grid.

Separately or in addition, in some normative embodiments, the broker service provider provides more wireless transmissions from the original wireless transmission capacity provider or other wireless transmission capacity provider (eg, another operator or another network). Find the capacity. This can be done by sending a message (or request) to the original wireless capacity provider or the other wireless capacity provider (or another network) to get more resources allocated by the broker service provider (step). 802).

When the broker service provider receives more capacity (step 803), it updates the capacity information in the capacity area grid (step 804) and reserves wireless transmit capacity for user C (step 805). In addition, the broker service provider requires the wireless transmit capacity provider to allocate the capacity of user C, as described with reference to FIG. 3 (step 308).

At step 708, the broker service provider notifies the user that the lack of wireless transmit capacity indicated in step 801 has been resolved, if necessary, and the user can resume normal operation.

Without limiting the scope of claims and their interpretation, some technical effects of one or more normative embodiments disclosed herein are listed below. The technical effect is efficient management of wireless transmit capacity based on available capacity and transmit capacity needs. Another technical effect is to provide additional wireless transmit capacity for the user if the initially given wireless transmit capacity is exhausted. Another technical effect is to provide a method and apparatus for reserving and allocating bandwidth for live broadcast transmission of an event.
